Blue-green algae Red Alert warning lifted – Colignan to Nichols Point on the Murray River


February 18, 2021


The high-level algal warning (Red Alert) for the lower Murray River from Colignan to Nichols Point has been cleared. Downstream the high alert warning remains in place for the river from Buronga to Wentworth Weir.


Blue-green algae occur naturally and can reproduce quickly in favourable conditions where there is still or slow-flowing water, abundant sunlight and sufficient levels of nutrients.


Blue-green algae usually appear as green paint-like scums on the water, near the edges, or as greenish clumps throughout the water. It makes the water appear dirty, green or discoloured and generally has a strong musty or earthy odour.


People who believe they may have been affected by blue-green algae are advised to seek medical advice.
